Circumference = (pi) x (diameter) = 13 pi = 40.841 feet(rounded)
2*pi*radius = circumference 2*pi*radius = 13 Making the radius the subject of the formula is: radius = 13/(2*pi) = 2.06901426 feet Check: 2*pi*2.06901426 = 13 feet
The circumference of a 13 inch round circle is: about 40.84 inches.To do this calculation for other circles, just multiply the diameter by Pi (about 3.1416). The result is the circumference.
13 pi or ~40in
81.7 cm
The radius of a circle with a circumference of 13 feet is: 2.069 feet.
The circumference is about 81.7 feet.
The circumference is about 81.7 feet.
Circumference = (pi) x (diameter) = 13 pi = 40.841 feet(rounded)
Circumference = pi x diameter = pi x 13 = 40.84 feet or 40'10"
Circumference = Pi x d: 13 = 3.14 x 13 = 40.82 feet
r = ~2.07 feet
radius in feet = 13/(2*pi)
Circumference of a circle is found by multiplying the diameter by pi (for general use pi is 3.14). 13 x 3.14 = 40.82 feet
Circumference = Pi x d: 3.14 x 13 = 40.82 feet
The circumference of a circle with a radius of 13 is: 81.68 units.
Circumference of a circle = diameter x (pi) = 13 pi = 40.841 feet (rounded)
